Apparatus and Method for Transmitting Content

1. An apparatus for transmitting content, comprising: a computer-readable storage medium storing one or more programs; at least one processor configured to execute the one or more programs stored in the computer-readable storage medium; and a communication bus connecting the processor and the computer readable storage medium, wherein the one or more programs includes one or more computer executable instructions configured to: transmit a request message for content requested by a client device to a plurality of content servers; calculate a response delay time of each of the plurality of content servers based on a response message of each of the content servers for the request message; determine one or more content servers to which a byte range request for the content is to be transmitted, from among the plurality of content servers, based on at least one of the response message and the response delay time and to determine a size of a byte range request and a number of byte range request for each of the one or more content servers; and acquire the content from the one or more content servers through the byte range request based on the size of a byte range request and the number of byte range requests; and determine the number of byte range requests to be proportional to the response delay time of each of the one or more content servers and to be inversely proportional to a number of connections to each of the one or more content servers.

2. The apparatus of claim 1 , wherein the one or more computer executable instructions is further configured to identify the plurality of content servers to which the request message is to be transmitted by using a domain name system (DNS) lookup.

3. The apparatus of claim 1 , wherein the one or more computer executable instructions is further configured to transmit the request message to a load balancer that performs load balancing on the plurality of content servers, receive the response message transmitted by the plurality of content servers from the load balancer, and identify the plurality of content servers to which the request message is to be transmitted based on information included in a header of the received response message.

4. The apparatus of claim 1 , wherein the one or more computer executable instructions is further configured to transmit the byte range request to each of the one or more content servers as many as the number of byte range requests of each of the one or more content servers and receive data for the content corresponding to the size of the byte range request of each of the one or more content servers out of a total size of the content from each of the one or more content servers, wherein the data for the content is divided by the number of byte range requests of each of the one or more content servers.

5. The apparatus of claim 4 , wherein the one or more computer executable instructions is further configured to acquire the content by combining the data for the content received from each of the one or more content servers.

6. A method of transmitting content, comprising: transmitting a request message for content requested by a client device to a plurality of content servers; calculating a response delay time of each of the plurality of content servers based on a response message of each of the content servers for the request message; determining one or more content servers to which a byte range request for the content is to be transmitted, from among the plurality of content servers, based on at least one of the response message and the response delay time; determining a size of a byte range request and a number of byte range request for each of the one or more content servers; and acquiring the content from the one or more content servers through the byte range request based on the size of a byte range request and the number of byte range requests, wherein the determining of the size of a byte range request and the number of byte range requests further comprises determining the number of byte range requests to be proportional to the response delay time of each of the one or more content servers and to be inversely proportional to a number of connections to each of the one or more content servers.

7. The method of claim 6 , wherein the transmitting of the request message further comprises identifying the plurality of content servers to which the request message is to be transmitted by using a domain name system (DNS) lookup.

8. The method of claim 6 , wherein the transmitting of the request message further comprises transmitting the request message to a load balancer that performs load balancing on the plurality of content servers, receiving the response message transmitted by the plurality of content servers from the load balancer, and identifying the plurality of content servers to which the request message is to be transmitted based on information included in a header of the received response message.

9. The method of claim 6 , wherein the acquiring further comprises transmitting the byte range request to each of the one or more content servers as many as the number of byte range requests of each of the one or more content servers and receiving data for the content corresponding to the size of the byte range request of each of the one or more content servers out of a total size of the content from each of the one or more content servers, wherein the data for the content is divided by the number of byte range requests of each of the one or more content servers.

10. The method of claim 9 , wherein the acquiring further comprises acquiring the content by combining the data for the content received from each of the one or more content servers.
